My invention belongs to that general class of devicesv known as heating apparatus, and more particularly relates to anv improved hot water heater, steam boiler or the like for use 5 wherever j found applicable. My invention has among Vits objects'the production of a device of the kind described that is simple, convenient, durable,-co mpact and efficient. It has particularly as an Aobject the production ofv 1c a device that will not onlybe rapid and sen# sitive in operation, but will likewise be par.- ticularly economical in use vas well as inexpensive in construction. Many other objects and advantages of the construction herein 15 shown and described will be obvious to those skilled inthe art from the disclosure'herein given. i

Tothis end my invention consists in the novel construction, arrangement and combi- 20 nation of parts herein shown and described, and more particularly pointed out in the claim.

In the drawings, wherein like reference characters indicate like or corresponding 2.5 parts;

Referringfor thev present to Figs. 1 to 6, inclusive, wherein VI have shown a preferred form of the invention embodiedin Va heater,

1926. Serial No. 119,101.

the reference character 15 designates generally the housing or setting for the heater, the setting k15 being formed of any suitable material, but being preferably constructed .I from bricks or other refractory material. In 55 this instance the setting 15 comprises Vfront and rear walls 1 6 and 17,1'espectively, side l walls 18 and a topwall 19. Disposed in the lower part of the setting 15 is a grate `2(),-or'

the equivalent, the grate being so positioned ce that the hot gases of combustion may flow upwardly through the setting tov a vflue 22 opening into the rear wall 17. -The iiue 22 is preferably provided with adamper 23 and a `check draft regulator 424. Access maybe had to an Vash pit 26 below the grate 20 through a door 27 suitably mounted upon the front wall 16, a similar ldoor 28being pro'- vided in the front wall 16 to permit the grate 2O to bev charged with coalor the equivalent. The purpose of a plurality of relatively large apertures31 formed in the front wall 16 will presently be described. It will be noted that these apertures 31 are normally closed by cov ers or doors 33 which may be movably secured to the front wall by any suitable` means.

Dispose-d in the setting 15 and positioned above the grate 2O Vare a plurality of substantially flat hollow memberswhich are identified by the reference characters 35, 36, 37 38, Se 39, 40 and 41, the hollow members being disposedone above the other in spaced relation. It will be noted that the lowermosthollow member is designatedv by the reference char acter 35 and that Athe uppermost hollow mem- 85 ber isdesignated bythe reference character 41. While the hollow members 35 to 41, inelusive, may be of any suitable shape and may be formed vfrom anysuitable material, I preferably form'them from cast ironv and 9@ give them a substantially rectangular shape. As best shown in Fig. 2, the setting 15 is substantially rectangular in cross section andv as best shown in Fig..3 the width of each of the hollowmembers 35 to 41, inclusive, is sub-V stantially equal to the distance betweenthe side walls 18-ofr the housing. And as shown in Fig. 1, the hollow members 35` to 41,-l inelusive, 'are preferably arranged in staggered -3 1 relation, the front ends of the hollow memi bers 35, 37, 39 and 41 being positioned against member 35 (see F ig. 5).

the front wall 16 and the rear ends of the hollow members 36, 38 and 40 being positioned against the rear wall 17. It is readily un- Vderstood that the hollow members 35 to 41,

inclusive, serve'as battles so that the hot gases of combustion must flow through a circuitous path as they pass from the :grate '20 to the iue 22'. The flow ofthe hot gases is indicated b-y arrows in Fig; 1. v

Thefhollow members 35 to 41, inclusive, may be supported within the setting 15 by any suitable means and in any suitable manner, but -Iprefer to support them by having the marginal edges thereof rest upon shoulders 43 formed in the walls of the setting.

'Ilo prevent kwarp-ing ofthe hollow members and also `to reinforce them against the action offpressures obtaining therein, I preferably provide a plurality of integral tubular 'mem- 'bers 45 'in each hollow member, the tubular members 45 preferably extending from 'the bottom -wall of eachv hollow 'member to the top thereof.' "For lreasons 'hereinafter' set forth, I preferablyV close the apertures ls o formed in the 'hollow fmembers to 41, inelusive, by buttons 46 or theV equivalent, each button 46 vpreferably comprising asha'nh 47 adapted to project into one of theapertures formed in the )hollow member and a head 46 flor preventing it from fail-ling therethrough,

The hollow Vmembers35 to 41, inclusive, preferably communicate with each other through a -pluralityof nipples 50,101 the equivalent, which are provided with `tapered ends 51 vadapted to seat in tapered apertures 52 formedA inthe walls of the hollow members (see If-ig. 4). T-he nipples 50 are sopositioned that tie rods 54`may extend `therethrough, the tie rods '54 preferably extending from above the top w'afll of the hollowmember 41 Ainto the bottom wall Aof ythe hollow The lower ends of the tie rods '54 are preferably screw-threaded into tapped holes 56 formed in the bottom wall of the hollow member and nuts '57 are preferably screw-threaded upon the upper ends of the tie rods in such mannert-lifat the 'nuts 'may be manipulated to tension `the tie the return pipe 60 communicates with the hollow member 35 through a pipe section 61,

the ret-urn pipe 60 being operatively connected to the pipe section V61 by an elbow 62. At `65 I have shown a feed water pipe which may be connected to any suitable supply (not shown) of water. Communication between the feed pipe 65 and the pipe section 61 is cont-rolled by a valve 66.

atively connected@ the return pipe 60 by other piping (not shown). The heater illustrated in F igs.r1 to 6, inclusive, is particularly adapted to be incorporated in a hot water heating system and the operation thereof is substantially as follows: Assuming that the discharge pipes 68 and the return pipe x60 have Vbeen operatively ,connected to -a plurality of radiators and assumi ingthat there is a sufficient supply of water in the system, .the valve 66 being closed, the hot gases of combustion will pass'between the hollow members 35 to'l41, inclusive, in the manner indicatedby the arrows in Fig.. l and the water within kthehollow memberswllabe heated. Obviously, the heated water will flow upward through the pipes 68 tothe radiators (not shown) and then return to the hollow members through the return pipe `60,

It is readily understood that the supply of water in the system may be replenishedlfnmlY time to time'by opening the valve 66,'whic'h then permits water to lowfrom .the 65 v into the system. i

The thickness of the hollow'membersto 4l, inclusive, may .beas desired, but .in fthe preferred embodiment of the invention I prefer-to make the uppermost and. lowermost hollow members of A:greater thickness .than the intermediate hollow members as the ne, turn and Adischarge pipes ,are connected to the lowermost and uppermost hollow members,

respectively. While Ifhaveshownjthehol'-4 low membersspacelequidistantly from leach other, it is to be understood that IFamnGt limited to .this arrangementas in some instances I prefer to vary the spacing. i

The heater shown in Figs. lto 6,' inclusive, isy exceedingly vefficient as lthe water being heated is being distributed in .relatively thin sheets in the hollow members yso that there iis an eliicient exchange of heat .between the hot gases of combustion and the water. The heater may be 'brought into effective operation in an extremely short` period oftime.

This is', of course, mainly .due to the fact that the water passes in relatively thin sheets ythrough theheater.. A feature of the invention is that deposits y.of soot -upon the hollow' Y members may be removed :through the aforementioned apertures 31 provided inthe front wall 16, thus insuring that the efficiency of the heater :will be maintained at all times.

Referring .to Figs. 7 and S-Ihav-e shown :another form of the invention-.embodied fin a within the sett-ing 70 in spaced relation and `inea/nas v heaterA particularly; adapted to be incorporated'in a steam heating system.. AThe heater.;

formed 0f anyv suitable material, ybut pref-- erably comprises brick or. any other refractory material. A grate orthe equivalent is preferably positione'dfin. the lower part of the setting 70, the hot gases of combustion rising from the grate bein discharged from the setting through a lue Y with the interior of thesetting through the rear wall 72. Fuel may be supplied to the grate 75 through a door 78 hinged tothe front wall 71 and ashes may be removed from the setting through a door 79 also hinged to the front wall. A plurality of relatively large apertures 80 are preferably provided in the front wall 71 for substantially the same purpose that the apertures 31 'are provided in the aforementioned front wall 16, the apertures 80 being normally closed by covers or doors 82. Hollow members resembling the aforementioned hollow members 35 to 41, in'- clusive, and designated by the reference characters 84, 85, 86, 87, 88, 89 and 90`are mounted are preferably supported upon shoulders 92 formed upon the interior surfaces of the walls thereof. Each of the hollow members 84 to 90, inclusive, is substantially equalin width to the distance between the side walls 73 so that the hot gases of combustion will not pass around the side edges thereof. As best shown in Fig. 7, the hollow members 84 to 90, inclusive, are arranged in staggered relation, the front edges of the hollow members 84, 86, 88 and 90 abutting the front wall 7l and the rear edges of the hollow members 85, 87 and 89 abutting the rear wall 72. A pipe 95 which communicates with the lowermost hollow member 84 is preferably employed as the v return pipe of a steam heating system, the pipe 95 being connected to the radiators (not shown) thereof. Steam may be discharged from the uppermost hollow member 90 through one or more discharge pipes 97 which are also connected to the radiators (not shown) of the steamheating system. The

' the construction shown in Figs. 1 to 6, inclu- 6 communicating sive'. The lowermosthol-low member 84 is preferably somewhat'thicker than the hollow members to 90, inclusive, as it receives the water from the return pipe'95. The uppermost hollow member is preferably'several times thicker than anyffoneyof the hollow members 84 to 89, inclusive, asv it servesas a steam `chamber.- As illustrated', the system preferably contains sufiicie'ntfwater to substantially fillthe hollow members 84'to 89, inclusive, and to partially lill the` hollow memberl90.f f i `The 'operation of the heater shown in Figs. 7 and 8 resembles the operation ofthe heaterk shown in Figs. 1` to 6, inclusive, and is sub# stantially .as follows: Assuming that al fire is burning upon the grate 17 5, thehot gases of combustion pass between the hollow members 84 to 90, inclusive, inthe manner indicated by the'arrows shown in Fig. y7. Steam is quickly generated in the hollow members and passes to the steam chamberor hollowmember 90k throughthe nipples 98, after which the steam passes to the radiators (notshown) of the steam heating system. through the pipes 97. When the steam condenses inthe radiyat'ors, it returns'to the hollow member 84 through the return pipe 95.' 'K r 1t will .be noted. thatv the hollow members 84 to 90, inclusive, are substantially vflat and that the hollow members 84 to 89,'inclusive,

are relatively thin so that there is an eicient exchange ofvheat between lthe hot gases of combustion and the water contained in-*the i hollow members.V The hollow-members 84 to 90, inclusive, are'preferably reinforced by integral tubular members which are substantially identical'in construction with the aforementioned tubular members 45. The apertures thus formed in the hollow members 84 to 90, inclusive, are preferably closedv by buttons 106 substantially identical with the aforementioned buttons 46. Y'

'Ihave shown still another form .of the inl vention embodied in a heater, the reference character 110 designatesasetting constructed from ybrick "or any Vother. suitable. material and provided Lwith side walls 111, a top wall 112 andfront'and rear walls 113V and 114-,respec-v tively. The setting 110 is preferably provided witha grate 115, or the equivalent, and a plurality of hollow members 117, 118, 119, 120, 121, ,122' and 128 are arranged'above the grate, the hollow members 117-to 123, inclusive, being substantially identical in Referring now to Figs. 9 and 10, wherein` A construction with the aforementioned hollow members 84 to 90, inclusive.: Each of thev hollow members 117 to 128,`inclusive, issubstantially equal inwidth to the distance between the side walls 111 andthe hollow members are preferably arranged in staggered ref lation in Vsubstantially* the same manner .as

the hollow members y85 to41, inclusive. The i hollow members 11710128 communicate'with '1,30

each other through' nipples 125, rods 126 eer-l tending through the nipplesV being aelfal'oted tosecure the .hollow members and the nipples to each other toform a substantially unitary l structure. Connected tol each ofthe liolilow VThe mains 128 and'lSO areadapted to eonneet a pluralityof radiatersor the equivalent tofthe heater.. l/Vater may be` introduced to the heating systemzthrough a pipe133 which: communicates with any suitable supply (not shown)A- owater. The flow of watery through the pipe 133' to: the main 128- is preferably controlled by a. valve 134.

The operation of the heater shown in Figs. 9l and l'Oissubstanti-alfly the sameI as the heater sho-wn'in Figs. 1 to 6', inclusive, with lthe exception that the heated water does notfnecessarily travel upwardly through the Vseveral hollow members before'passi-ng.I to tlieradiators et' the system. Obviously, the water may beheatedf in a minimum of time asv the water may flow into any @ne of' the holle-w members from the return pipe and then, when heated, pass directly into the discharge pipe.v In the embodiment ot the invention shown in Figs; 1 te 6, inclusive, the water enters the lowermost hollow member and travels up.- ward through the other hollow members to the discharge pipe. l

` In boirl'ers embodying my invention the het gases must travel back and forthbetweenvthe sheets of water inthe hollow members and as ticularl-y adaptable for gas heaters, especiaL' 'ly of a small type'such as are used-,for heating bathrooms and' other small enclosures.

'Having thus deseri'bedf my invention, it is obvious that variousimmaterial modili-cations may be madre in the same without d'eparting from the spirit' of my invention;

hence l do. not wish tolbe understood as limitingmyself' to` the exact form, construction,

arrangement andi combination of parts here- 1n shown and describedl ory uses mentloned.

What l claim as new and desireto secure vby Letters Patent is:

In a boiler forheating dwellingsor the like, comprising front, rear and'side walls, a pluralirty of verticall,7 spaced substantially flat Vhollow members :arranged as baffles within saidv walls, integraltubular reinforcing members extending through each of said hollow members, closures'for said reinforcing vmeinbers, nipples disposed betweenV said hollow members andbeveled therein, tie rods extending; through the nipples and. hbllolw members for securing said members fixed relationtoeach other and te the boiler casing, a Huid inlet pipe communieatingwith the lower` most. ofI said hollowy "members, anda dis- .0
